One is a flawed mercenary and the other is a medicated psychopath, but that hasn't stopped Kane & Lynch from making their way to Xbox Live in demo form, having appeared on PlayStation Network earlier this month.

We left our Xbox 360 at home today because it's cold and we wanted to walk down the road with our hands in our pockets, so we can't tell you what's in it, but we can tell you that the description promises "hard-edged criminal action" in addition to "back-stabbing online", which sounds about right.

When it's assembled on your hard disk it will be occupying 520.04MB according to the fastidious Major Nelson, which compares favourably albeit irrelevantly to however big the other one was on PSN.

Anyway, you can learn more about Kane & Lynch: Dead Men in our Kane & Lynch: Dead Men review, where Kristan argues that it delivers on some counts, but not enough others to help it stand out from other "duck and cover" shooters like Gears of War and Uncharted: Drake's Fortune.
